watchdog is always fully optional in distros. Even in x86 where there
is watchdog hardware on every new chipset. It is rare to even see the
kernel modules to enable watchdog loaded (they don't autoprobe for
some reason), let alone the userspace to tickle it.

I thought things were now at the point where orion5x/etc were just
needing a dts file and testing? Is there any more code work required?
Sebastian's IRQ and timer changes seemed like the last of it?

Doesn't appended dtb already work?

I didn't think bootloader support was a gating item to run with DT??
